Description
When the platform of the ‘Liquid Whirler’ rotates, the water in the frame is propelled outwards by this force. As a result, it takes on the shape of a parabola. This is the same force you feel when taking a sharp turn in a car and are pushed towards the outside of the turn.
The principle of centrifugal force is used in many industries, such as in centrifuges used in laboratories and medical facilities to separate substances based on density. It is also used in amusement parks in attractions that rotate rapidly, such as the carousel.
Did you know that a dryer works in the same way? When you spin wet clothes rapidly, the water is thrown outwards. The water passes through the holes in the drum, but the clothes do not. This is how your clothes become drier.
Why do your clothes become drier in a centrifuge?
- Rotate the platform.
- Observe what happens to the water.
- How can you compare this to a centrifuge?
